Inhibitors generally refer to gonadotropin-releasing hormone analogs (GnRHa), which are mainly used for the treatment of central precocious puberty. How long it takes to return to normal growth after discontinuing the use of GnRHa varies from person to person, and sex hormones, bone age, and other tests can be regularly rechecked. GnRHa is mainly used for the treatment of central precocious puberty, through the inhibition of hypothalamic-pituitary-gonadal axis activity and sex hormone secretion, so that the gonadotropin secretion function is reduced to pre-pubertal level, slowing down the progression of bone age of the children, so as to improve the height of adults, and can be used in conjunction with growth hormone. How long it takes to return to normal growth after discontinuation varies from person to person, and sex hormone and bone age tests can be repeated periodically for a comprehensive assessment of growth and development. Adverse effects of this drug are common in girls who experience small amounts of vaginal bleeding, redness, swelling and pain at the injection site. Cautious use of the drug is required. Patients are advised to use this drug under the guidance of a doctor and not to use it privately.
